ICAO has emphasized that aeronautical information agencies should provide digitized data and information, realize exchanging internationally in AIM. The AIXM structured dataset will be the main source of basic exchange network. In this article, authors first analyze spatio-temporal attributes design query method obstacle based on research coding specification. Secondly, helicopter path planning is taken as scenario. Using route dataset, combining performance constraints to construct envelope frame for collision judgment, a new with improving classical A* algorithm proposed. proposed validated visualized. validation results show reduces frequency turning, ensures safe distance between flight obstacles.
